PropertyTest

Struct PropertyTest 

Source
pub struct PropertyTest { /* private fields */ }
Expand description

Property-based test runner.

TigerStyle:

  • Deterministic via seed
  • Explicit operation count limits
  • Invariant checking after each operation
  • Time advancement control

Implementations§

Source§

impl PropertyTest

Source

pub fn new(seed: u64) -> Self

Create a new property test with the given seed.

§Panics

Panics if max_operations would exceed DST_SIMULATION_STEPS_MAX.

Source

pub fn with_max_operations(self, max: u64) -> Self

Set the maximum number of operations to run.

§Panics

Panics if max exceeds DST_SIMULATION_STEPS_MAX.

Source

pub fn with_time_advance(self, config: TimeAdvanceConfig) -> Self

Configure time advancement between operations.

Source

pub fn skip_initial_invariant_check(self) -> Self

Disable checking invariants before the first operation.

Source

pub fn run<T: PropertyTestable>(self, state: T) -> PropertyTestResult

Run the property test.

Generates random operations, applies them, and checks invariants after each operation. Returns detailed results.

Source

pub fn run_and_assert<T: PropertyTestable>(self, state: T)

Run the property test, panicking on failure.

Convenience method for use in #test functions.

§Panics

Panics if any invariant is violated.
